Title: Spindle motor
Inventor: SAKATANI IKUNORI
IPC: F16C33/12
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To suppress the lack of load carrying capacity of a radial bearing, as well as to suppress the whirling vibration, even though the inside of a spindle motor is made in a high temperature condition at high speed rotation. SOLUTION: The setting position of the axial center P direction of an electromagnetic drive motor 19 is positioned between two radial bearings 38 and 40 provided by separating in the axial center direction. As a result, even though an uneven radial load is generated by the slippage of the coaxial level of the electromagnetic drive motor, the radial load is distributed to two radial bearings, and the moment load is never loaded onto the radial bearings. Since a bearing member 8 and rotary bodies 18 and 20 are formed of a material with almost the same heat expansion coefficient, the relative position of the fixing parts of the bearing member and the rotary bodies are hardly changed even in a high temperature atmosphere, so as to suppress the whirling vibration of the bearing member and the rotary bodies.  Since a fixing shaft 34 and the bearing member are formed of the material with almost the same heat expansion coefficient, the bearing clearance of the radial bearings is hardly changed even in a high temperature atmosphere.
